Why Electric Knife Sharpeners Are Better Than Others?

best professional electric knife sharpener

There are many reasons why electric knife sharpeners are better than others. Maybe it’s a little bit expensive but not all sharpeners costly. Even I have explained some reasonable electric sharpeners which are really affordable even than your knife. Now let me talk about how electric sharpeners are best than others?

Time-Saving: If you compare an electric sharpener with a sharpening stone so course it is a time-saving machine. Because everything does the power motor and abrasives belt, you just need to drag the blade on the sharpening slot. Even no need for any manual sharpening angle.

No Skills Required: If you use a sharpening steel or rod then you have to know about it. Because without the right sharpening angle you may lose blades edge. But in the electric sharpener has automatic sharpening function and angle that helps for a beginner if they don’t know how to sharpen a knife?

Does not Damage Knives: There are many expensive Japanese and European style blade which required high care and maintenance. And this care can extend the edge retention and performance. But only in electric sharpeners have Diamond abrasives and ceramic polishing wheel which can give you a nice razor-sharp and clean blade.

Keeps You Safe: Only an electric sharpener provides the best safety than a manual sharpener. Because for sharpening a knife you just have to hold the handle and drag the blade on the slot. And there is no stupid mechanism that can hurt you. After sharpening use a tomato or paper to test the blade sharpness.

Suitable for Different Knives: Many sharpeners can handle only kitchen and hunting knife. But an electric sharpener can handle all kinds of kitchen knives, serrated knives, butcher knife, paring knife, fillet knife, boning knife, Japanese knife, hunting knife, pocket knife,  skinning knife, and many others. So if you need to sharpen various knives then an electric sharpener is the right choice for you.

How Electric Knife Sharpener Works?

The main question about, how electric knife sharpener works? The electric sharpener provides the user with ease in terms of usage. You just have to switch it on and the abrasives. That does the grinding task to smooth out the distorted straight edge of a knife. So the sharpener motorized on the wheels that spin against the dull knife smoothing out the edges. And it’s much Annoying to use dull knives in the kitchen. So a Pro electric knife sharpener will give you the best opportunity to sharpen your kitchen or commercial knives. But there are only a few sharpeners can handle hunting and other knives.

When the kitchen knives are inserted inside the slot wheels with abrasives makes the task as mentioned. The task of the sharpening process is easy as you don’t need to apply any force to get the work done. With light pressure, you insert the knife in the slots. And pull the knife back after inserting slowly so that both sides of the blade are smoothened.

In addition, most electric sharpeners have 3 to 4 different grinding slots. Each slot provides different coarseness to provide variety in sharpness. You can choose the amount of sharpness you wish. Also, the electric sharpener has the ability to narrow the angle of a knife blade. And it can without any stoppage convert a western blade from 20-degrees in a 15-degree sharpening angle.

It has guides loaded with springs restricting the movement of the knife. Due to this feature, the whole length of the knife blade gets smoothen making great contact with the abrasives at a precise sharpening angle. Furthermore, by sharpening your knife with an electric sharpener there won’t be daily chaos of sharpening.

How Often Should A Knife Need Sharpening?

This is a very common question, and everyone tries to find the correct answer. But actually it will depend on your everyday uses, blade style, and materials. Because people use a knife for different kitchen jobs such as cutting and slicing, mincing or dicing, chopping even for cutting frozen meat.

The sharpening stone is a good way for sharpening all kinds of kitchen and outdoor knives. But this process is time-consuming, not very safe, and stone eats deep metal. But if you use an electric sharpener then it will give you a razor-sharp blade within a few minutes and retain the edge for a long time. Due to this, no need for regular sharpening. But you regularly chopping a lot of vegetables then you should sharpen your knife minimum once a week.

How You Should Choose The Best Electric Knife Sharpener?

kitchen knife sharpener

To sharpen your knife if you are interested to buy the best electric knife sharpener so you should consider some features which may give you the best safety and Convenience. In your budget, you should choose those sharpeners that can fulfill your needs. Let’s see which thing you should consider?

Sharpening Stages

Most electric sharpeners available with 2 or 3 stages for sharpening kitchen and outdoor knives. Three-stage sharpeners have different slots these are, coarse, honing, and polishing. This means these features will give you more razor-sharp, clean edge, and better shiny blade but it would expensive and ideal for professionals.

On the other hand, two-stage sharpeners are very simple but don’t have much precision like 3 stage sharpener. But it provides slightly the same performance and less expensive. If you are a home cook, then it would be the best choice for you. Because it’s easy to use and maintenance.

Sharpening Abrasive

People love electric sharpener because it has either diamond abrasive, or Sapphirite sharpening wheel. Both features only to deliver a clean and razor-sharp blade. The diamond abrasive is very effective because it’s the hardest material. Even if you have a deeply dull knife then this function will give your knife a previous super sharp edge.

Other hand Sapphirite sharpening wheel is a good alternative of diamond abrasive. It is the same ultra-hard material even that use the most professional knife sharpening shop. Especially this feature is available with 2 stage sharpener and it’s very affordable. But actually it will depend on you what kind of knife you want to sharpen and which feature will be best in your budget?

Angle Guide

Angle guide is very important, especially for beginners. Even I would say sometimes professional chefs need a special device to measure the right angle. This function makes knife sharpening easier and popular than a manual. So if you want to use an electric sharpener for your first time, then you should look at it.


Versatility is not very important if you need to sharpen only kitchen knives. But if you want to sharpen several knives in one machine then you should choose a sharpener that have the ability to handle kitchen and outdoor knives.

Even you should choose that sharpener can handle stainless steel blade, Japanese knives, or bread/serrated knife. But if you need a sharpener only for a kitchen knife, then you should avoid a versatile sharpener. Because that would expensive.


The electric sharpener is not very lightweight, because it has a motor, grinding stone, and made from high-quality materials. But always if you need to carry it, then choose a lightweight sharpener. Unfortunately, without electricity, you can’t use it outdoor. But above I have explained some sharpeners that operate by the battery. That means if you charge them fully, then you can use it outdoor no need any electricity.

Safety Features

The electric sharpener is one of the safest ways to sharpen a knife. Because this machine designed to reduce any injury during sharpening. Some sharpeners have a special handle to hold it by hand while using it.

But if the sharpener has a special suction cup on the bottom then it will fit in any situation and it will prevent moving the sharpener. That’s why you can sharpen your knife with ease and easy, no need to hold the sharpener.


A knife is the most important part of everyday cooking. And when your kitchen knife moving to dull. So, of course, that is needed to buy a new knife. But it is not the right decision to buy a new knife every time only to sharpen.  If you think a manual knife sharpener is difficult to use and that takes more time.

So easily you can buy an electric sharpener and electric sharpener means not a high price at all the time. Even, already I have introduced some best electric knife sharpeners which are available at a reasonable price. I hope now easily you can choose your sharpener for your kitchen and outdoor knives. And I would say, the electric knife sharpener is very important for every home and professional kitchen now and then.
